“…To improve steady-state performance for conventional MPC, many researchers explore the idea with multiple voltage vectors instead of one voltage vector in every sample interval [14,15]. Wang et al [14] used DVMPTC to track reference VV for five-phase PMSM control, which offers good steady-state performance and simple control structure. M.L.…”

Due to the application of only one voltage vector in a control period, conventional model predictive torque control (MPTC) suffers from relatively large steady‐state ripples. The‐state‐of‐the‐art double‐vector‐based MPTC (DVMPTC) was proposed to improve steady‐state performance. However, its duty cycle optimization method significantly affects the control performances. Thus, MPTC with hybrid mode duty cycle optimization is proposed, which realizes better performance than the universal DVMPTC, and obtains the appropriate average switching frequency, especially at high‐speed domain. The proposed method utilises the universal DVMPTC method, while it equips duty cycle optimization with discrete space vector modulation (DSVM) scheme as the additional constraint for further reducing the reference voltage tracking error that exists in DVMPTC. What's more, rotation module and pre‐selection strategies are involved in simplifying the design of vector selection methods. Comparative simulations and experiments verify the effectiveness of the proposed method.

Multi-phase motors are effective for the aforementioned applications because they can be driven using non-fault phases when some phases fail [9][10].…”

This paper presents reverse-phase superimposition method for motor fault-tolerance to reduce torque ripple while maintaining torque level under motor winding fault situation. When a motor winding fails, two problems occur: the torque level decreases, and the torque ripple increases. Although previous research solved these problems, maintaining the torque level and reducing the torque ripple simultaneously has not been possible. In the proposed method, the current under the fault condition is separated into zero-, positive-, and reverse-phase, and the reverse-phase current is superimposed on the non-fault phase. By using the proposed method, the torque ripple can be suppressed while maintaining torque levels. To validate the effectiveness, numerical and experimental verification was conducted, and results obtained by the proposed method were compared with the torque performance of the conventional methods. The results revealed that with the proposed method, the advantages of the two conventional methods can be obtained together.

“…Owing to the advantages of high efficiency, high power density, and wide speed range, a permanent magnet synchronous motor (PMSM) is favored for industrial applications [1]. Compared with the traditional three-phase PMSM, the five-phase fault-tolerant PMSM (FTPMSM) owns the merits of reduced power per phase, lower torque ripples, and better fault-tolerant capacity, which has received innovative research and rapid development in high-reliability applications such as aviation actuators, electric vehicle drive systems, and ship propulsion systems [2,3].…”

Research on Fault-Tolerant Field-Oriented Control of a Five-Phase Permanent Magnet Motor Based on Disturbance Adaption

et al. 2022

View full text Add to dashboard Cite

To ensure the high-quality output performance of the five-phase fault-tolerant permanent magnet synchronous motor (FTPMSM) drive system under normal and open-circuit faults and achieve the minimal reconfiguration of the FTPMSM control drive system under various open-circuit faults, in this paper, a fault-tolerant field-oriented control (FOC) strategy based on disturbance adaption is proposed. The speed-loop and current-loop steady-healthy controllers are designed to effectively suppress the torque ripples caused by open-circuit faults and improve the robustness of the drive system to load disturbance and motor parameter variation under fault operation. Moreover, the additional zero-sequence current controller can be omitted. In addition, the modified reduced-order coordinate transformation matrices are proposed to weaken the influence of oscillating neutral. Finally, the fault-tolerant FOC system of the FTPMSM is established, and its experiment is conducted. The experimental results verify the feasibility and effectiveness of the proposed control strategy.
